Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a self-generating structure for a rowing machine. Background Technology

[0002] Rowing machines are designed for training purposes and are used to simulate rowing on water. They are effective in strengthening the muscles of the legs, waist, upper limbs, chest, and back.

[0003] Existing rowing machines are already equipped with self-generating structures. For example, the patent with publication number CN222368291U shows a self-generating transmission structure for rowing machines. This structure converts the mechanical energy generated during rowing into electrical energy to power the electronic equipment (such as displays and sensors) of the rowing machine.

[0004] For the self-generating transmission structure of this patent, when the generator is connected to the transmission mechanism, it is necessary to machine a wheel groove for belt connection on the driven wheel set of the transmission mechanism separately. When the generator is connected to the power mechanism, it is necessary to additionally install a generator drive belt pulley on the drive wheel of the power mechanism.

[0005] Both of these connection methods are structurally complex. Whether it's machining grooves on the driven pulley set or adding an extra generator drive pulley, both inevitably increase the number of steps in the production process, making it difficult to control production costs and subsequent maintenance and disassembly. Furthermore, when the generator is connected to the driven pulley set, the power generated by the power mechanism will experience some energy loss during transmission through the transmission mechanism, which also affects the generator's power generation efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a self-generating structure for a rowing machine, which can improve power generation efficiency while effectively simplifying the production process and controlling production costs.

[0007] To achieve the above objectives, the solution of this utility model is: a self-generating structure for a rowing machine, comprising a power unit, a double-groove pulley, a resistance unit, and a generator;

[0008] The power unit is installed on the rowing machine, and the rowing motion of the human body provides power to the power unit. The double-grooved pulley is rotatably connected to the power unit. The resistance unit is installed on the rowing machine and is driven by one of the pulley grooves. The generator is driven by the other pulley groove.

[0009] In a preferred embodiment, the diameter of one groove of the double-groove pulley is smaller than the diameter of the other groove.

[0010] In a preferred embodiment, the system further includes a generator belt, wherein the other groove of the double-groove pulley is connected to the generator shaft via the generator belt.

One end of the spiral spring assembly is fixed at the axis of the drive wheel, and the other end of the spiral spring assembly is snapped and fixed to the inner wall of the drive wheel.

[0012] In a preferred embodiment, a one-way bearing is also included, which is mounted on a double-groove pulley, and the double-groove pulley is coaxially connected to the drive wheel via the one-way bearing.

[0013] In a preferred embodiment, the system further includes a transmission unit, through which the resistance unit is connected to one of the wheel grooves.

[0014] In a preferred embodiment, the transmission unit includes a main belt and a driven pulley set, one of the grooves of the double-groove pulley is connected to the driven pulley set via the main belt, and the driven pulley set is connected to the resistance unit.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] This embodiment provides a self-generating structure for a rowing machine, such as... Figure 1 As shown, it includes a power unit 1, a double-groove pulley 2, a resistance unit, and a generator 30;

[0027] The power unit 1 is installed on the rowing machine. The rowing motion of the human body provides power to the power unit 1. The double-groove pulley 2 is rotatably connected to the power unit 1. The resistance unit is installed on the rowing machine and is driven by one of the wheel grooves 20. The generator 30 is driven by the other wheel groove 20.

[0028] When the user is performing rowing motion, the power of the power unit 1 is transmitted to the resistance unit (not shown in the figure) which is connected to one of the grooves 20 of the double-grooved pulley 2. At the same time, in this embodiment, the generator 30 is connected to the other groove 20 of the double-grooved pulley 2, so that the power of the power unit 1 can be directly transmitted to the generator 30. The power transmission process is more direct and effectively improves the power generation efficiency.

[0029] The double-groove pulley 2 in this embodiment can adopt an existing structure, which is beneficial for production and processing and cost control, and also facilitates later maintenance and loading / unloading processes.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the diameter of one groove 20 of the double-groove pulley 2 is smaller than the diameter of the other groove 20, but this is not the only limitation. This design allows the resistance unit and generator 30 connected to the double-groove pulley 2 to have different transmission ratios when the power unit 1 transmits power to the double-groove pulley 2. This ensures the exercise effect while improving the power generation efficiency of the generator 30, demonstrating a clever design. Of course, in other embodiments, the user can adjust the diameters of the two grooves 20 of the double-groove pulley 2 according to actual needs.

[0031] like Figure 1 As shown, it also includes a generator belt 31, and the other groove 20 of the double-groove pulley 2 is connected to the shaft of the generator 30 through the generator belt 31.

[0032] In this embodiment, the generator 30 is directly connected to the other groove 20 of the double groove pulley 2 via the generator belt 31. The structure is simple, and it can be easily repaired or replaced when a fault or wear occurs. The manufacturing cost is also relatively low.

[0033] Furthermore, the power unit 1 includes a traction member 10, a drive wheel 11, and a spiral spring assembly for coordinating with the human rowing motion. The traction member 10 is wound around the drive wheel 11 to drive the drive wheel 11 to rotate. The drive wheel 11 is coaxially rotatably connected to the double-groove pulley 2. One end of the spiral spring assembly is fixed at the axis of the drive wheel 11, and the other end of the spiral spring assembly is snapped and fixed to the inner wall of the drive wheel 11.

[0034] In this embodiment, the traction member 10 is used to assist in the rowing motion of the human body. The traction member 10 is connected to the drive wheel 11, and the drive wheel 11 has a spiral spring assembly inside. When the user performs rowing motion through the traction member 10, power is generated and transmitted to the drive wheel 11. The spiral spring assembly (not shown in the figure) is twisted, thereby driving the double-groove pulley 2 to rotate the generator 30 to generate electricity. The structure is simple.

[0035] Furthermore, it also includes a one-way bearing, which is mounted on the double-groove pulley 2, and the double-groove pulley 2 is coaxially connected to the drive wheel 11 through the one-way bearing.

[0036] In this embodiment, a one-way bearing is installed on the double-grooved pulley 2. When the user performs a rowing motion using the traction member 10, the power generated is transmitted to the drive wheel 11. The spiral spring assembly (not shown in the figure) is twisted, and the drive wheel 11 rotates in the forward direction. This causes the double-grooved pulley 2 to drive the generator 30 to rotate in the forward direction to generate electricity. When the user releases the traction member 10, the spiral spring assembly, under the action of torque, drives the drive wheel 11 to rotate in the reverse direction. Because a one-way bearing is installed on the double-grooved pulley 2, the double-grooved pulley 2 will not rotate in the reverse direction synchronously, and the generator 30 will not generate electricity. Therefore, the power generation process in this embodiment is intermittent. Of course, in other embodiments, a one-way bearing may not be installed on the double-grooved pulley 2 according to actual needs, so that the generator 30 can generate electricity continuously.

[0037] like Figure 1 As shown, it also includes a transmission unit 4, and the resistance unit is connected to one of the wheel grooves 20 through the transmission unit 4.

[0038] In this embodiment, the resistance unit is connected to one of the wheel grooves 20 via the transmission unit 4. When the user adjusts the resistance of the resistance unit, the transmission unit 4 can transmit the resistance change in a timely and accurate manner, making the adjustment process of the resistance unit more user-friendly.

[0039] like Figure 1As shown, the transmission unit 4 includes a main belt 40 and a driven pulley set 41. One of the grooves 20 of the double-groove pulley 2 is connected to the driven pulley set 41 via the main belt 40. The driven pulley set 41 is connected to the resistance unit.

[0040] In this embodiment, one groove 20 of the double-groove pulley 2 is connected to the driven pulley group 41 via the main belt 40, which is simple in structure. The driven pulley group 41 is connected to the resistance unit. The resistance of the resistance unit is adjusted and then applied to the double-groove pulley 2 and the power unit 1 after passing through the driven pulley group 41. On the one hand, the resistance transmission can be optimized, making the adjustment process of the resistance unit more user-friendly. On the other hand, it also makes the distribution of each unit on the rowing machine more flexible.

[0041] like Figure 1 As shown, it also includes a control board 51 and an electronic meter, which are mounted on the rowing machine. The control board 51 is electrically connected to the generator 30 and the electronic meter, respectively, for transmitting electrical energy and data to the electronic meter.

[0042] In this embodiment, the control board 51 is electrically connected to the generator 30 via the connecting cable 50. In addition to monitoring the working status of the generator 30 in real time and ensuring that it operates within the normal parameter range, the control board 51 can also transmit relevant data parameters to an electronic display (not shown in the figure) for easy viewing by the user.

[0043] The directional terms used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0044] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
